使用For循环在列表中查找最大值

def find_max_value(lst):
    if not lst:
        return None
    
    max_value = lst[0]
    for value in lst:
        if value > max_value:
            max_value = value
    
    return max_value

# 示例列表
numbers = [3, 5, 1, 8, 2, 10, 4]

# 查找最大值
max_value = find_max_value(numbers)
print(f"列表中的最大值是: {max_value}")

def find_max_value(lst):
    if not lst:
        return None
    
    max_value = lst[0]
    for value in lst:
        if value > max_value:
            max_value = value
    
    return max_value

def find_max_value(lst):
    if not lst:
        return None
    
    max_value = None
    for value in lst:
        if isinstance(value, (int, float)):
            if max_value is None or value > max_value:
                max_value = value
    
    return max_value
